Transforaminal Interbody Lumbar fusion is a surgery that is used to cure spinal weakness or instability by uniting lumbar or lower spine bones permanently. 

TLIF surgery aims to remove or decompress the pressure from the spinal cord nerves,  spine stabilization, and preventing further degradation at the joint.

Transforaminal Interbody Lumbar Fusion (TILF)

  • Degenerative disc disease with a specific discogenic pain pattern.
  • Low grade 1 or grade 2 spondylolisthesis.

  • Previous decompression for a herniated disc.
  • Decompression in association with micro-instability, spondylolisthesis

Transforaminal Interbody Lumbar Fusion (TILF):Pre-Procedure

 A full physical examination will be conducted by the doctor to see if the patient is in good health to undertake the surgery.

  • The disc space is entered and disc material is removed.
  • The bone graft is obtained from the patient’s iliac crest (the hip).
  • A spacer or interbody cage that is filled with bone graft is placed into the disc space to maintain the disc height.

  • Pedicle screws are attached to rods or plates.
  • The wound is closed.
